Intelligent data management in cloud computing

In big data era, data management is a hot topic. People have to face large amounts of data, which will occupy much local storage space. Cloud computing provides the storage services for people with the manner of pay-as-you-go. In order to save the storage 'resources, people will store their data in the remote cloud servers. In this way, the storage resources are greatly saved. In this paper, jwe focus on the management of the remote data. A novel management scheme is proposed for the outsourced data. A new attribute- abased access control technique is introduced to enhance the security of the data. If the user does not satisfy the access policy, he/she cannot get the real information. Our scheme is secure and efficient.
